    • A memory system and a method for operating a memory system are provided. The memory system includes a set of memory banks, logic for calculating a first address in each memory bank from the set of memory banks and a controller receiving a transfer address from a computing device. The controller includes logic for selecting a memory bank from the set of memory banks based on the transfer address and the first addresses of the memory banks, and for mapping the transfer address to a target address in the selected memory bank based on a first address in the selected memory bank. As a result, the set of memory banks has a contiguous memory space.
